The production channel as privilege risk.
When attorney-client privileged documents are produced in litigation discovery, the channel used for production matters legally. An inadvertent disclosure through an unsecured email server, or documents visible to a cloud provider's employees under their terms of service, can trigger privilege waiver arguments. Courts in multiple jurisdictions have been inconsistent; the safest position is to eliminate the argument entirely by using a zero-knowledge relay where the infrastructure operator cannot read what it carries.
Chain of custody is the second issue. Rule 26(b)(5)(A) under the US Federal Rules of Civil Procedure (and equivalent provisions in EU jurisdictions) requires that a party claiming privilege identify the documents withheld and describe them sufficiently to allow an assessment of the claim. That description requires knowing exactly what was delivered, when, and to whom. Standard email does not provide tamper-evident delivery records; a cryptographic receipt does.
Zero-knowledge relay with a tamper-evident receipt.
Paramant encrypts the production set with ML-KEM-768 + AES-256-GCM. The relay holds only the ciphertext and cannot read the documents. After opposing counsel downloads, the relay wipes its copy. The ML-DSA-65 signed receipt records the SHA-256 hash of the delivered package, the recipient's delivery address, and the timestamp — exactly the information needed to establish chain of custody and to support a Rule 26(b)(5)(A) privilege log.
No US CLOUD Act exposure for EU litigation. EU/DE hosting means the infrastructure is not subject to US law enforcement production orders that could compromise privileged material.
From production set to opposing counsel.
What Paramant does and does not do.
Paramant handles the delivery channel. It does not review documents for privilege, does not conduct keyword culling, and does not generate a privilege log. It provides a tamper-evident delivery record and a zero-knowledge infrastructure. Your e-discovery review platform and your legal team handle the review and log generation; Paramant handles the production delivery in a way that does not add new evidentiary problems to the ones you already have to manage.
